Method Detail

invoke

public java.lang.Object invoke(java.lang.Object target,
                               java.lang.String methodName)
                        throws java.lang.NoSuchMethodException,
                               java.lang.reflect.InvocationTargetException,
                               java.lang.IllegalAccessException

forClass

public static BeanSetter forClass(java.lang.Class c)
                           throws EncapsulatedException

Gets the BeanSetter for a particlar class.

Parameters:

c - the class for which we want the BeanSetter

Returns:

instance to manipulate instances of the given type

initialize

public void initialize(java.lang.Object obj,
                       BeanDefinition def)
                throws BeanFactoryException

Initializes an object given a context and a set of bean attributes. The constructors are responsible for handling resolution of references between objects. This method is problematic in both multi-threaded environments as well as with self- and mutual-reference situations. A near-term enhancement will to be to add some kind of "Intitialization Frame" which will help solve both problems.

Parameters:

obj - the object to be initialized

ctx - BeanContext that owns the object

attrs - attributes that define the bean

getIndexedProperty

public java.lang.Object getIndexedProperty(java.lang.Object target,
                                           java.lang.String name,
                                           int idx)
                                    throws PropertyNotFoundException,
                                           EncapsulatedException
